# Topic: Regular open set

###### In the News (Fri 24 May 13)

 Free regular set - Wikipedia, the free encyclopedia In mathematics, a free regular set is a subset of a topological space that is acted upon disjointly under a given group action. The set of points at which G is freely discontinuous is called the free regular set and is sometimes denoted by Ω = Ω(G). is the free regular set of the modular group Γ on the upper half-plane H. en.wikipedia.org /wiki/Free_regular_set   (217 words)

 Topology glossary - Wikipedia, the free encyclopedia The boundary (or frontier) of a set is the set's closure minus its interior. Equivalently, the boundary of a set is the intersection of its closure with the closure of its complement. Idempotence: The closure of the closure of a set is equal to the closure of that set. en.wikipedia.org /wiki/Topology_Glossary   (4707 words)

 Regular Expressions Regular expressions are a context-independent syntax that can represent a wide variety of character sets and character set orderings, where these character sets are interpreted according to the current locale. In the regular expression processing described in this specification, the newline character is regarded as an ordinary character and both a period and a non-matching list can match one. A bracket expression (an expression enclosed in square brackets, []) is an RE that matches a single collating element contained in the non-empty set of collating elements represented by the bracket expression. www.opengroup.org /onlinepubs/007908799/xbd/re.html   (5095 words)

 Open Adoption: A True Life Experience In "open" adoption the secrecy of years gone by is replaced by trust between the adopting couple and the birthparent/s. Open adoption allows the child to know s/he has two sets of parents who love her, the "real" Mommy and Daddy who are parenting her and the birthparents who loved her enough to choose a better life for her. We have discovered that the sibling participating in an open adoption can be the object of the jealousy of a sibling without access to her birth family. www.adopting.org /Nanci/open.html   (1232 words)

 PlanetMath: separation axioms The separation axioms are additional conditions which may be required to a topological space in order to ensure that some particular types of sets can be separated by open sets, thus avoiding certain pathological cases. given two distinct points, there is an open set containing exactly one of them; point and a compact set in a Hausdorff space have disjoint open neighborhoods. planetmath.org /encyclopedia/Regular.html   (509 words)

 ./_Man_SunOS_4.1.3_html/html2/open.2v.html When this flag is set, and path refers to a terminal device, open() prevents the terminal device from becoming the controlling terminal for the process. The ``set group ID on execution'' bit of the mode is cleared if the effective user ID of the process is not super-user and the process is not a member of the group of the created file. There is a system enforced limit on the number of open file descriptors per process, whose value is returned by the getdtablesize.2 call. www.cs.rit.edu /~hpb/Man/_Man_SunOS_4.1.3_html/html2/open.2v.html   (1169 words)

 Proof Set Packaging Examples All Proof Sets issued from 1936 to 1972 include the cent, nickel, dime, quarter and half dollar; from 1973 till 1981 the dollar was added and then removed from the sets in 1982. Sets from 1999 were available both as a regular copper-nickel clad composition for the dime, quarter and half dollar and in the 90% silver for these coins. The 1960 set is somewhat easier to see the difference between the large "0" in the large-date set and small "0" in the small-date set date especially when comparing the two sets side-by-side. www.jakesmp.com /GP_Proof_sets/GP_Proof_sets_100_C.html   (1591 words)

 Regular expressions Regular expressions have a syntax in which a few characters are special constructs and the rest are "ordinary". The result is a regular expression which matches a string if A matches some amount of the beginning of that string and B matches the rest of the string. Because `\\' quotes special characters, `\\\$' is a regular expression which matches only `\$', and `\\[' is a regular expression which matches only `[', etc. Note: for historical compatibility, special characters are treated as ordinary ones if they are in contexts where their special meanings make no sense. virtual.park.uga.edu /humcomp/perl/regular_expressions.HTML   (1595 words)

 open(2) open opens a file descriptor for the file named path and sets the file status flags according to the value of oflag. When open is invoked to open a named stream, and the connld module (see connld(7)) has been pushed on the pipe, open blocks until the server process has issued an I_RECVFD ioctl (see streamio(7)) to receive the file descriptor. Open file descriptors are a process resource and available to any sibling thread; if used concurrently, actions by one thread can interfere with those of a sibling. ou800doc.caldera.com /en/man/html.2/open.2.html   (1489 words)

 CONSTRUCT SET [Set_Name] REMOVE Parts are then removed from the set if all of their primary defining parts satisfy the test (ie end points of lines are considered, but points defining the centres of arcs are not). Sets that have been created with the default options will be automatically completed, so that all parts used in the definition of higher order parts will be added to the set. Elements in block 1 of an IJK regular model having I values of 1 to Imax, a J value of 3 and K values 10 to 20 are removed from all open sets. www.princeton.edu /~dynaflow/femgv/manuals/userman/node89.htm   (1302 words)

 open The open() function shall return a file descriptor for the named file that is the lowest file descriptor not currently open for that process. The open file description is new, and therefore the file descriptor shall not share it with any other process in the system. If O_CREAT is set and the file did not previously exist, upon successful completion, open() shall mark for update the st_atime, st_ctime, and st_mtime fields of the file and the st_ctime and st_mtime fields of the parent directory. www.opengroup.org /onlinepubs/009695399/functions/open.html   (2568 words)

 How To Use Regular Expressions in Microsoft Visual Basic 6.0 Regular expressions allow simple parsing and matching of strings to a specific pattern. If you use the objects that are available in the Microsoft VBScript Regular Expressions 5.5 library, you can compare a string against a specific pattern, replace a string pattern with another string, or retrieve only portions of a formatted string. Global: Sets a Boolean value or returns a Boolean value that indicates whether a pattern must match all the occurrences in a whole search string, or whether a pattern must match just the first occurrence. support.microsoft.com /default.aspx?scid=kb;en-us;818802   (606 words)

 open(), open64() -- open a file The open file description is new, and therefore the file descriptor does not share it with any other process in the system. If set, the file offset is set to the end of the file prior to each write. If set, the file is deleted when the last file descriptor referring to it is closed. www.mkssoftware.com /docs/man3/open.3.asp   (1103 words)

 Cultured Perl: Perl 6 grammars and regular expressions Reusing regular expressions to match a single word is ridiculous; reusing them when parsing a configuration file is almost a necessity (depending on the complexity of the configuration syntax, how often it changes, and so on). Well, it usually is. There are modifiers to the regular expressions, both inside and outside the expression: case-insensitivity, lookahead, multiple matches, ignoring whitespace, number of matches, and so on. Damian Conway calls Perl 5 regular expressions "arcane, baroque, inconsistent, and obscure," which shows he is biased in their favor. www-106.ibm.com /developerworks/linux/library/l-cpregex.html   (2987 words)

 Python re Module - Use Regular Expressions with Python - Regex Support The backslash is a metacharacter in regular expressions, and is used to escape other metacharacters. Regular expression objects are more efficient, and make your code more readable.

 Setting Up Shop Open source is simply a new (really, newly popularized) way of developing, distributing, and licensing software, and for companies which understand the economic, cultural, and political factors that go into implementing an effective open-source strategy, the open-source model offers the promise of helping your business better survive and thrive in an increasingly demanding environment. For a company considering adopting an open-source strategy, open source needs to be evaluated from a business point of view and not just as "a good thing to do." That requires being clear on the advantages and disadvantages of open source relative to the traditional model. However the provisions of the Open Source Definition and of open-source licenses can also be seen not just as guarantees to users in general but also as guarantees to software developers in particular, that they will be treated fairly and given equal opportunity to succeed or fail based on their merits. www.hecker.org /writings/setting-up-shop   (14193 words)

 Getstats 3.0 Set Commands It must be set before any read commands are issued since it will be applied to any log records that do not contain a vhost field. We recommend setting domlevels to 2 because 1 level does not provide enough detail in the domain reports, and 3 levels requires too much memory.

 O'Reilly Network -- Using Regular Expressions in PostgreSQL Regular expressions, for the uninitiated, are a set of key combinations that allow people to search for character matches, thus enabling a large variety of control in a text environment. Regular expressions are a staple of the Unix-like operating systems, although they are virtually unknown in one notable exception (go ahead and guess). Regular expressions offer the DBA the ability to compose queries using highly complex criteria in a compact and sophisticated manner. www.oreillynet.com /pub/a/databases/2006/02/02/postgresq_regexes.html   (656 words)

 XML Schema Reference: Regular Expressions A regular expression is a pattern for identifying a range of string values.

 Smart Software: Regular Expression Performance Constructing the regular expression typically takes time due to parsing, but the Regex class will cache previously used regular expression to eliminate the parsing cost for the same pattern, passed in a future constructor. For one things, these “regular expressions” include numerous additional features that capture phenomena that can’t be represented in regular languages, and thus can’t be represented by a simple state machine (at least, without the addition of a stack or two). The is because regular expressions, for literal text, use Boyer-Moore searching which typically uses N/M checks versus the simplistic N*M searching algorithm that String.IndexOf algorithm uses, where N is the length of text and M is the length of the pattern. wesnerm.blogs.com /net_undocumented/2005/05/regular_express.html   (1133 words)
